Where dоes thаt rоаd gо? How does а television work? What is that tool used for? Answering these questions may have no obvious benefit for you. Exploration and curiosity appear to be motives directed toward no more specific a goal than “finding out.” Even animals will learn a behavior just to be allowed to explore the environment. Animals also seem to prefer complexity, presumably because more complex forms take longer to know and are therefore more interesting. Placed in a maze that is painted black, a rat will explore it and learn its way around. The next time, given a choice between a black maze and a blue one, it will choose the blue one. Apparently the unfamiliarity of the unknown maze has more appeal. 1. The passage implies that curiosity

Reаd the fоllоwing pаssаge frоm an essay on culture by American anthropologist Clyde Kluckhohn (1905–1960). Then choose which statement is most logically supported by the information. promiscuous: active sexually and relatively unselective about sexual partners celibacy: going without sexual activity reciprocities: exchanges Every culture must deal with the sexual instinct. Some, however, seek to deny all sexual expression before marriage, whereas a Polynesian adolescent who was not promiscuous° would be distinctly abnormal. Some cultures enforce lifelong monogamy, while others, like our own, tolerate serial monogamy; in still other cultures, two or more women may be joined to one man or several men to a single woman. Homosexuality has been a permitted pattern in the Greco-Roman world, in parts of Islam, and in various primitive tribes. Large portions of the population of Tibet, and of Christendom at some places and periods, have practiced complete celibacy°. To us marriage is first and foremost an arrangement between two individuals. In many more societies marriage is merely one facet of a complicated set of reciprocities°, economic and otherwise, between two families or two clans.

Reаd the fоllоwing pаssаge. Then chоose which statement is most logically supported by the information. The goal of our lives must be to reach out in kindness, love, and care. We must change the world by our relationships with other people- that will be our immortality. We will not be remembered for job or financial success. There is no gravestone that say, "Effective CEO" or "A Multimillionaire." Hopefully our grave will have words such as "Loving father" or Devoted daughter" or "Caring husband" or "Beloved sister.
